Description
The Comet P36/10GR is a high-volume, low-to-medium pressure diaphragm pump designed for professional-grade spraying. This model comes pre-equipped with a gearbox (GR), allowing it to be mounted directly to a gasoline engine with a 3/4″ shaft. It is a favorite for those who need more volume than a standard 12V pump can provide but don’t require the extreme high pressure of a pest control pump.
Key Features & Performance
-
High Volume Output: Delivers a powerful 9.3 GPM, making it ideal for large-scale applications where covering ground quickly is essential.
-
Low-Maintenance Design: Engineered for reliability with a semi-hydraulic two-diaphragm system that ensures a smooth, consistent spray.
-
Direct Drive Gearbox: The integrated gearbox reduces the engine’s high RPM to the pump’s ideal operating speed, providing a compact and efficient power transfer without belts or pulleys.
-
Chemical Resistant Components: Built with materials designed to handle common agricultural chemicals, fertilizers, and herbicides.
